(Sun T1/2000s aside). This is basically the same patch from a few months ago, with updated offsets. If you don't define MAXCPU in the kernel config, it reverts to old behavior. It has no logic to keep you from shooting yourself in the foot though.. you can define options SMP and options MAXCPU 128 on arm. --- Harrison Grundy
